gnu.io.PortInUseException and lock file issues

I'm not the first to post similar issues, but I've found no relief from existing solutions.

I'm getting a variety of serial comm issues, but most of them seem to revolve around gnu.io.PortInUseException: Unknown Application and lock file issues.

I'm connecting using an arduino + BlueSmirf bluetooth mudule. CoolTerm has absolutely no issue connecting so I'm fairly certain its related to processing. If I manually remove the lock file, and start things just right, every once in a while I get a successful connection, so I know that generally speaking the connection settings are correct. But for the most part I get some kind of connection error. The permissions on the lock folder are 777, but I do notice that the lock files themselves are read only.

I'll include errors below for fun. Thanks for any ideas.
